  name : str
      Display name of chart
  plot_type : str
      Identifier of chart type
  plot_component : str
      Identifier of Arena's component that should render this chart
  plot_category : str
      Name of category of chart
  params : dict
      Dictionary with required param types as keys and param labels as values.

docstr: Tests if plot can be created for at least one combination of params
  
  This method searches for params, that can produce valid chart. Displaying
  error messages are not counted as valid. One example of usage are charts for
  classification models. Such charts should override this method and check if
  there is at least one classification model in arena.
  
  Parameters
  -----------
  arena : dalex.Arena
      Object of class dalex.Arena
  
  Returns
  -----------
  bool
